PIPE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 656,956, dated August28, 1900. Application filed July 14, 1899. Serial No. 723,838. (Nomodel.)

To all whom it may concern:

Be it known that I, CARL EIBEE, of the city of New York, borough'ofBrooklyn, in the county of Kings and State of New York, have invented anew and Improved Pipe-Oouplin g, of which the following is a full,clear, and exact description.

My invention ,relates to a pipe-coupling adapted for connecting sectionsof hose or for connecting a hose to a hydrant or other source ofwater-supply.

The object of the invention is to provide a simple yet effectivestructure whereby a coupling-section and a mating section may be quicklylocked together and rendered water or fluid proof where they connect andas quickly and conveniently separated under all conditions of weather.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of the improved coupling attached to ahydrant. Fig; 2 is a plan view of the coupling adapted for use on ahydrant, a portion of the clamp used in connection therewith beingbroken away; Fig. 3 is a face view of one coupling-head for a hose. Fig.1 is a face View of the mating coupling-head. Fig. 5 is a horizontalsection through the two coupling-heads when united. Fig. 6 is a verticalsection through the united coupling-heads, illustrating the applicationthereto of a separating device, WhlChdGVlGQ is in section. Fig. 7 is .anend view of the separating device shown in Fig. 6. Fig. Sis a sectionthrough a modified form of the coupling especially adapted forattachment to a faucet; and'Fig. 9 is a side elevation of the centralportion of the clamp shown in Figs. 1 and 2, the view being drawn on anenlarged scale.

When the coupling is to be used to unite or connect twosections of hose,two couplingheads A and B are employed. A U-shaped flange or bar 10isoffset from the front face of the coupling-head A, being connectedwith said face at opposite sides by cheek-pieces 14,

whose outer surfaces extend beyond the outer side portions of thecoupling-head, as shown in Fig. 3. Thus an opening 11 is formed at thebottom of the head A, between the flange 10 and front face of thehead,'and slideways 1O" are obtained at the sides of the head. A hood 12is constructed at the upper front portion of the head A, the front faceof which is in the same plane with the front face of the coupling-head,and a recess 13 is produced in the front face of the hood. The matingcoupling-head Bis provided with a transverse tongue 15 at its frontface, formed by producing a U-shaped recess 15 in the exterior of thehead B at the sides and bottom, as shown in dotted lines in Fig. 4 andin positive lines in Fig. 5. In coupling the tongue 15 of the head Benters the slideways 10 in the opening 11 in the head A, While at thesame time the flange 10 of the coupling-head A is received in the groove15 of the head B. The coupling-head B is also provided with exterioroffset side faces 16, which strengthen the head and mate with thecheekpieces 14. A hood 18 is formed upon the upper portion of thecoupling-head l3, adapt ed to mate with the hood 12, the front face ofthe hood 18 being flat and in the same plane with the front face of thecoupling-head A B, and in the hood 18 a pin 19 has horizontal movement,adapted, when the two heads are coupled, to enter the recess 13 of thehood 12, as shown in Fig. 6. This pin is attached to a thumb-piece 20,having an offset 21 upon its under face, adapted to slide in a groove 22in the upper portion of the body of the coupling-head B, as is shown inFig. 6. The

coupling-head B is also provided with an exterior lug 17 at its bottomjust back of the groove 15, andthis lug is adapted to assist in theuncoupling of the two heads when secured together in the event theweather is exceedingly cold or in the event the two heads should becometoo tightly interlocked. In such an event it is simply necessary tostrike the lug 17 upon a firm surface, whereupon the tongue 15 will bedriven upward and out from the groove 10, the pin 19 having beendisconnected from the head A.

. Under some circumstances it'is necessary to provide a releasingdevice'to effectually and quickly separate the coupled or mating ICU.section 23 and an upper section 24, the two sections having a hingedconnection 25 at one end, terminating at the opposite ends'ininterlocking aper'tured knuckles 26, and a pin 27 is passed through theapertures of these knuckles 26 to convert said body into aclamping-ring. The pin 27 is connected with a lug 28 upon the uppermember of the body by means of a suitable chain 29. The shank or bottomportion of the releasing device 0 consists of a single angle-arm 30, theupright portion of the arm being secured to the ringbody, and the saidarm 30 is adapted to fit to the under surface of the coupled heads A andB. The horizontal portion of the arm 30 terminates in a socket 31, intowhich socket the lug17 of the head 13 is made to enter, and'thereleasing device is held on the head A by means of a ring-body 23 24,which is located around the sleeve portion of the head.

A screw 32 is made to enter the arm 30 of the releasing device andengage with the bottom of the lug 17, the said screw being provided witha bar 33 in order that it may be readily turned. Thus it will beobserved that by turning the screw 32 in a suitable direction, the latch19 having been drawn from engagement with the head A, the tongue 15 ofthe head B may be forced out from the slideways 10 of the head A.

In Figs. 1 and 2 I have illustrated a coupling especially adapted forattachment to hydrants. This coupling consists of a head A, constructedpractically as set forth and shown in Fig. 3; but instead of the groove10 receiving a tongue 15 the said groove receives a gate or slide D,which is the equivalent of the said tongue 15, as shown in Fig. 1. Thisgate or slide is attached to the hydrant by means of a suitable chain36, so that the gate or slide cannot be lost. When the gate or slide isin position on the head A, the water cannot escape from the hydrant andthe gate is firmly held in position by a yoke 37, which engages with theouter faces of the cheekpieces 14 of the head A, as shown in Fig. 2. Ascrew 38 is loosely passed through the central portion of this yoke,being screwed or otherwise securely fastened to the central portion ofthe gate D. The head 39 of this screw is in the form of a nut, and thenut is provided with a lug 40, adapted for engagementwith a pin oroffset 41, forming a portion of the yoke, as is shown in Figs. 2 and 9.The nut 39 is first placed in position upon the outer end of the screw38, the yoke 37 is then slipped upon the screw, and, lastly, the screwis secured to the gate D. The lug 40 on the nut 39 bears such relationto the pin 41 on the yoke that the nut can be given almost one completeturn, and therefore cannot be removed from the screw and lost when theparts have been assembled. When the nut 39 has been turned in onedirection, the

yoke can move on the screw sufficiently to permit the end members of theyoke being free from clamping engagement with the cheek-pieces 14, andthe gate may therefore be entered into or removed from the slideways 10of the coupling-head. When the gate is imposition and the nut 39 isscrewed inward orin opposition to its releasing movement, the nut willforce the yoke in direction of the coupling-head and cause its endmembers to be brought into clamping-or binding engagement with the outersurfaces of the cheeks 14. It is not necessary that a watertightconnection be preserved between the gate D and the head A, as when thegate is in closed position the water is turned off at the hydrant. Thegate D simply acts to close the nozzle of the hydrant, and the yoke andits screw serve the purpose of retaining the gate in place. In fact, thegate D is a substitute for a cap and can be more readily removed thanthe ordinary cap and being connected with the hydrant or its nozzle inthe manner described is not liable to be lost.

In Fig. 8 I have illustrated a slight modifi cation, the coupling hereshown being especially adapted for attachment to the threaded portion ofa faucet. The only difference consists in a different form of latch andmeans for operating the latch. In this instance the latch consists of apin 42 having a large head 43, the pin being adapted to slide in asuitable opening in the hood 12 of the coupling head A, and the head ofthe pin enters a recess in the hood 18 of the coupling-head B. The pin42 is held in looking engagement with the coupling-head B by means of aspring 44, coiled around the reduced portion of the pin, and a lever 45,fulcru med upon the outer surface of the sleeve portion of thecouplinghead A, is pivotally attached to the pin 42, and by moving thelever 45 toward the sleeve of the coupling-head A the pin 42 iswithdrawn from engagement with the mating head B.

The gate or slide D is provided with an upper lug 35, to which the chain36 is attached, and a lowerlug 34, which corresponds to the lug 17 onthe coupling-head B, which lug 34 may be tapped by a hammer or anequivalent device should the gate or slide refuse to move from the headwhen ordinary force is brought to bear upon it.

Having thus described my invention, I claim as new and desire to securebyLetters Patent- 1. The combination of a coupling-section, and amating'section having a transverse tongue-and-grooved connection, one ofsaid parts having an exterior projecting surface vice consisting of aring-body fitted to the section mating with that having the saidexteriorly-projected surface, and an arm connected with the body,provided with a socket to receive said exterior1y-projeeted surface,together with a screw carried by the said arm and arranged forengagement with the said projected surface of the coupling-section, forthe purpose specified.
